Application led January 20,1906. Serial No. 296,970.

To alf/ZZ wir/071e it puny con/cern:

Be it known that I, Josnrn E. JOHNSON, a citizen of the United States,and a resident of Rochester, in the county of Monroe and State of NewYork, have invented certain new and useful Improvements in TubularLanterns, of which the following is a specification.

This invention relates to tubular lanterns; and it consists in themechanism hereinafter described and claimed.

The object of the invention is to improve and to cheapen theconstruction of lanternfonts in. combination with the gallery and theburner-holder.

ln the drawings, Figure l is a vertical section through a lantern-font,including its gallery and burner-holder and embodying this invention;and Fig. 2 is a vertical section through a portion of the top of alanternfont t rough the gallery before the parts are fastened togetherand otherwise finished.

ThisI invention is intended to improve the construction of lantern-fontsas to the connection of the gallery therewith and subordinately to thisconnection the connection of the burner-holder with these parts.

The lantern-font l has a top 2, that is made with a central perforation3. The sheet metal around the perforation 3 is bent downward from thetop 2 of the font into the posii tion shown in Fig. 2, thus forming alip o1' ledge 4 around the edge of the perforation 3, and a bead' orannular bend 5 depends from the said top. The gallery 6 is formed withan integral bottom 7, having a central perforation 8. Around theperiphery of the bottom is formed a bead 9, which can pass through thedepression in the top 2 of the font and rest upon the depressed rim 4around the perforation 3. In the walls of the gallery 6 are punched the'perforations l() l0 for the air-tubes, the said perforations beingdiametrically opposite to each other and at equal distances from thebottom 7 of the gallery-blank. The distances from the lower edges of theperforations l() 10 to the bottom of the gallery-blank are suchthat-When the parts are pressed together, asshown in Fig. 1, in theirpermanent positions the said bottoms of said perforations will registerWith the upper surface of the font 2, so that when the ends of theair-tubes are placed in the perforations l() l0, as usual, the adj acontair portions of the air-tubes will lie directly upon the top of thefont.

The bead 9 is made as a hrst stop of such size that it may pass throughthe opening in the top of lthe font 2 and into position upon the lip orledge l. Then the parts are placed in suitable dies, and thegallery-Walls are pressed downward toward the bottom of the gallery, soas to spread and enlarge the bead 9, and at the same time the bead 5depend-v ing from the top 2 of the font, is pressed to fit closelyaround the bead 9, and the parts then take the permanent and solidpositions shown in Fig. l.

In order to fasten the burner-holder l1 in place, the said holder isprovided with an inturned lip 12, and the parts are thus fastenedtogether. Of course the bending of a lip forming part of theburner-holder around the edge of the perforation 8 in the bottom of thegallery is the equivalent of the construction just described.

What l claim isl. The combination of a lantern-font having a perforationin its top and a bead formed adjacent to said perforation, a galleryhaving a perforated bottom, a peripheral bead around said bottom fittingin the bead in the top of the lantern-font, and a burner-holder attachedto the edge of the perforation in the bottom of said gallery. j

2. The combination of a lantern-font having a perforation in its top anda bead formed adjacent to said perforation and below the top of" thefont, a tubular gallery having a perforated bottom and air-tube holes inits sides, and a peripheral bead around said bottom fitting in the beadin the top of the lantern-font the said two beads being crushed togetherwhereby the air tube holes are brought into registry with the topsurface of the lantern-font.

3. The combination of a lantern-font havingy a perforation in its topand a bead formed adjacent to said perforation and below the top of thefont, a tubular gallery having a tern-font, and a burner-holder attachedto perforated bottom and air-tube holes in its the edge of theperforation irl the bottom of' sides, a peripheral bead around saidbottom said gallery.
